Expert Insight: The Brains Behind Your Comfort
The BCM in your GMT800 platform vehicle, like the Escalade, acts as a traffic controller for dozens of electronic functions. Over time, heat cycles, vibration, and simple electronic age can cause internal components and solder joints to fail, leading to the erratic behavior you’re seeing. Many owners waste time and money replacing individual switches or motors, only to find the root cause was the BCM all along. By installing a fully tested and properly programmed 2003-2006 Escalade ESV body control module, you’re not just fixing a symptom; you’re restoring the core of your vehicle’s electronic nervous system for renewed reliability.
Frequently Asked Questions
Will I need to have this BCM programmed by a dealer?
No. We pre-program the module to your vehicle’s VIN before it ships. This makes the installation a simple plug-and-play process, saving you time and the high cost of dealership programming.
What tools are needed for installation?
Installation is straightforward and typically requires only basic hand tools, like a socket set or screwdriver, to access the panel under the steering column where the BCM is located. The entire process often takes less than 15 minutes.
My airbag light is on. Will this fix it?
This BCM can resolve airbag light issues caused by communication errors (like DTC B1001). However, after installation, if the light remains on, a simple “Setup SDM Primary Key in BCM” procedure may need to be performed with a professional scan tool to sync the airbag system.

This 2003-2006 Escalade ESV body control module is a direct fit for the models listed. It also interchanges with numerous other GM trucks and SUVs from the same era. To confirm, you can match the part number from your original BCM to one of the compatible numbers listed in our description.
Is there a core charge?
No, there is no core charge for this part. You can keep your old module without the hassle of returning it.
